“PDF Nomad” looks like a fairly powerful and versatile PDF product in which you can do a lot. At $19.99 it’s a good price for it’s capabilities. It almost strikes me as if it is capable like PDF Pen from Smile Software which is a lot more money for it would appear to be similar capabilities.
Then I think about the Adobe products which PDF Pen is definitely taking on and they are very expensive. So for us Mac users we have a fair number of options. However, this one seems like a pretty safe bet at this price.
